I ported CharTranslator.py over from the Sabnzbd+ version to NZBGet. It has been tested by a friend of mine who owns a Synology and he confirmed that his movie files are added to the SynoIndex. This was the only thing keeping him from using NZBGet on his Synology and I figured I would share it for everyone. Feel free to test and report back with any errors or issues.

The script will fix the encoding issues after unpack and add the media files to the Syno DLNA Index
